I’m not sure if this is a bug or not, but I’ve set up four music loops with four markers.

Part 1, 2, 3, and 4.

I have Transition Regions and loop regions that are a part of each one. I’ve linked it to an intesety parameter.

When I first start playing it, it’s looping fine on part one. However, if I switch to part 2, the playhead completely vanishes. It then plays part of part 2 then goes to a part of 3 and the continues to loop at incorrect positions. However, if I tab over to the Intensity tab and then tab back, the playhead is where it’s suppose to be and it loops properly.

When the cursor disappears, it is going into the transition timelines associated with each of the transition regions you created.

Transition timelines link two points on the timeline in a non-instantaneous transition, as opposed to the instantaneous transitions that occur by default. They’re usually created whenever you double-click on a transition marker or transition region marker; I’m guessing you did this at some point while setting up the transition regions.

You can remove the transition timelines by right-clicking on each of the transition markers and selecting the ‘Remove Transition Timeline’ menu item. (Note that this doesn’t remove the transitions – just the transition timelines attached to them.)
